The present invention is designed to prove and simplify spray nozzles. lVith such nozzles it is desirable to deflect the spray laterally and in many locations control the spray so that its flow will be comparatively low, thus protecting windows and other walls adjacent to where the spray is in use. It is also desirable to have this adjustable so that the deflection of the spray may be adjusted in a manner to adapt it for the location in use, and where the adjustment is ac-complished by a screw to have means provided whereby the friction-al engagement of the screw may be made such as to assure the maintenance of the adjustment. It is also desirable to offer as little resistance to the flow of water through the nozzle as possible. The present invention is designed to provide a spray nozzle capable of carrying out the V above suggestions in a practical manner.

Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows Fig. l shows a central vertical section of the nozzle.

Fig. 2 a section on the line 2-2 in Fig. 1. 1 marks the body of the nozzle. This has an interior screw thread 2 by means of which the nozzle is attached to a fitting 3 carried by a support 4.

The upper end of the body has a smooth wall 5 and a spreading member 6 has an eX- terior wall fitting the Wall 5 and a screw thread 7 at its lower end fitting the screw thread 2. The member has an opening 6a extending through its bottom end into which the water passes in going through the body. It is provided with a slit 8 by means of which the lower end of the member maybe slightly expanded if desired and this makes a spring fit of the screw at the lower end of the memv ber and assures such frictional engagement withY thescrew 2 as to lockl thev spreading member in adjustment in th'e'body. i

'The spreading member isprovided-with a deflecting head 9 having the inclined, or defleeting surface l()l around itsV under edge. The member hasV radially disposed slots "11 which extend from the central opening Ga v throughthe wall' ofthe member. Theupper ends of the vslots are curvedv and upwardly A inclined'` at l2. The slots are preferably 55 formed by a milling operatonwhich-makes 'a curved cut in the exterior surface and thus affords this inclir'ratior'l;V These slots are' also slightly expandingtoward the outersurface n so asto `aid in the spreading ofthe spray. '60 With this structurev it will be seen that there is very little obstruction to the water, there being a free open passage through the spraying member andthatl the radially dise posed, or deflecting openingswith the de'- '65 fleeting head while-they do break the water into a sp-raypand deflect it still accomplishv this with as little resistance as possible. Further the construction as a whole is very simple I in thatthe samegscrew thread whicli'operates 70 for the fitting also accords means `for connecting the spreading member withthe body.
